1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

introductionThe ergonomic aspects of retrograde intrarenal stone surgery (RIRS) remain underexplored, despite their crucial role in minimizing musculoskeletal strain among surgeons and enhancing procedural efficiency. This study introduces a novel "Gun-holding" surgical posture for RIRS, aiming to improve surgeons' physical well-being and extend their operative careers. MATERIALS AND

methodsFrom July 2023 to June 2024, a total of 60 patients were prospectively enrolled from an initial pool of 104 and were randomized into two groups: the "Gun-holding" surgical posture group (Group A, n = 30) and the conventional surgical posture group (Group B, n = 30). Patient demographics, clinical outcomes, ergonomic assessments, and torque analysis for surgeons were analyzed.

resultsBaseline characteristics and stone burden were comparable between the two groups. Torque analysis demonstrated a higher upper limb torque ratio in Group A compared to Group B. Ergonomic evaluation revealed a significant advantage for Group A (total score: 16.1 ± 4.1 vs. 22.4 ± 9.1, P = 0.001). Group A also had a significantly shorter mean hospitalization duration (1.7 ± 0.9 days vs. 2.9 ± 1.9 days, P = 0.003). Although the mean operative time for Group A was shorter (49.9 ± 26.1 min vs. 63.0 ± 40.4 min), this difference was not statistically significant (P = 0.139). No significant differences were observed in initial stone-free status (SFS), 3-month SFR, postoperative Day 1 hemoglobin drop, or overall complication rates.

conclusionThe "Gun-holding" surgical posture is a feasible, efficient, and safe alternative for performing RIRS, offering significant ergonomic benefits to surgeons.
